Drivers should prepare for delays east of Snoqualmie PassFebruary 20, 2017

(HYAK, WA.) – Drivers should prepare for delays east of Snoqualmie Pass this week due to single-lane daytime closures and full nighttime closures of Interstate 90.

Starting this Wednesday, Feb. 22 through Friday, Feb. 24 the Washington State Department of Transportation (WSDOT) will have single-lane closures in both directions from 8 a.m. to 4:30 p.m. just east of the Snoqualmie Pass summit.

WSDOT will also close I-90 at night. The westbound lanes will close from 10 p.m. to 5 a.m. at milepost 62 near the Stampede Pass interchange and the eastbound lanes will close from 11 p.m. to 6 a.m. at milepost 56 near the Gold Creek area.

WSDOT will reopen the lanes during the nighttime closure every two hours to clear out traffic.

Reason for the closures

In an effort to improve visibility and safety at night on I-90, crews are installing additional reflectors along barriers and installing LED lane markers where possible.

Crews are also removing built-up snow in the lanes along Keechelus Lake and cleaning the road dirt off the side panels to improve reflectivity.

A reduced speed of 45-miles per hour at night will assist drivers navigating through the eastbound lanes east of the summit; the temporary speed reduction will be in effect until visibility along the lake improves.
